10 Claims.

This invention relates to a striping or banding machine, the presentapplication being an improvement over the subject matter of ourapplication Serial No. '707,958 filed January 23, 1934,

l the improvement increasing the efficiency of the machine.

This invention also consists in certain other features of constructionand in the combination and arrangement of the several parts to be here-10 inafter fully described, illustrated in the accompanying drawings andspecifically pointed out in the appended claims.

In describing the invention in detail, reference will be had to theaccompanying drawings where- 15 in like characters denote like orcorresponding parts throughout the several views, and in which:

the vacuum means for holding a glass in position.

Figure 13 is a vertical sectional view showing Y supporting structuresupporting a tubular shaft on which is xed a rotary circular table Ihaving bearing members 2 thereon for radial shafts 3, the outer end ofwhich carry the means for supporting the glassware or the like shown atA in 5 Figures 1 and 13. Shaft 3 has a beveled gear 4 on its inner endwhich mesh with a beveled gear 5 attached to the upper end of aconstantly driven shaft, not shown and which has a portion passingthrough the tubular shaft. This constantly driven shaft rotates thetubular shaft by a Geneva gear shown at 6 in dotted lines in Figure land a disk 1 having a projection thereon engaging the slots of theGeneva gear so that the table I is intermittently rotated while theshafts 3 are constantly rotated. As before stated these parts are fullydescribed and illustrated in the above mentioned application. Mounted onthe frame is an applicator station and while the drawings show but onestation as manyk of these stations can be provided as desired or inaccordance with the number of shafts which rotatably support theglassware. A bar I0 is supported by the frame and has an elongated slotII therein which slidingly receives the reduced lower end of a forkedmember I2 whichis secured in adjusted position on the bar by a bolt andwasher shown at I3 in Figure 2. A sectional arm I4 has one end pivotedbetween the prongs I5 at the upper end of the forked member, the otherend of this section having a socket therein for receiving the stud I6 ofthe second section I1 so that the section I1 is rotatably connected withthe section I4 and said section I1 is held in adjusted position by a setscrew I8 threaded in ahole in the section I4 and engages the stud I6.The outer end of the section I1 is forked to provide the prongs I9 whichrotatably support between them the applicator wheel 20. As shown moreparticularly in Figure 3 the prongs I9 are provided with threaded holesfor receiving the set screws 2I having taperedinner ends formed withsubstantially semi-spherical recesses lfor receiving the balls 22 whichare pressed into the ends of a centrally arranged bore 23 formed in thehub of the wheel 20. These balls 22 are held against rotary movement inthe ends of the bore and rotate in the recesses in the screws 2I. The vsame arrangement is used for the bearing means 24 at the outer end ofthe section I4 of the arm as shown at 24 in Figure 5. The prongs I5 asWell as the prongs I9 are slightly resilient so that blows or the likestruck the arm or the Wheel will cause a slight movement of the prongsand thus prevent damage to the parts and permit the parts to return tonormal position after being struck.

The prongs I5 extend toward the wheel as shown at I5' in Figure 2 and aleaf spring 25 rests partly on the shoulder formed at the junction ofthe prongs with the part I2 and has one end fastenedl to the shoulderforming part by a screw 26, the spring tending to move upwardly at itsother end but such movement is limited by the stops 21 on the lowerportion of the outer parts of the prongs as shown in Figure 6. Each ofthe prongs I5 and I9 is split as shown at 28, the split extending intothe screw receiving opening and the splitl portions are adjustablyconnected together by the screws 29.

A screw 30 passes through a threaded hole in the section I4 of the armand engages the free end of the spring 25, as shown inl Figure 2, thisscrew and springfornting adjustable yieldable means for holding the armand wheel in a certain position.

As will be understood a plurality of wheels must be furnished with theapparatus, the wheels being interchangeable and of diierent shapes andsizes. Figures 3, 11 and 12 show wide wheels for the application of widebands to the articles and in these wide wheels the circumferences aregrooved'as at 3I, these grooves efficiently applying coating material tothe article in an even and smooth manner. The wheel shown in Figure 3has what might be termed a flat peripheral edge while that shown at 20in Figure 11 has a convexed edge and that shown at`20" in Figure 12 hasa concave edge. It will of course be understood that a certain kind ofwheel must be used for certain kinds and shapes of articles.

The wheel picks up the coating material from a pan 32 as in the beforementioned application and a scraper assembly shown at 33 is provided forpreventing too much of the coating material being carried to the articleby the wheel. 'This assembly comprises a plate 34 of spring material andhaving one end reduced and perforated to receive a screw 35 whichconnects said end with the lower part of the section I1 of the arm. Theother end of the plate is cut away at its central portion as shown at 36and the edges left by this cut away portion are bent into loop form asshown at 31 to provide spring jaws for holding a cartridge or container38, shown in Figure 9, which is of substantially U-shape and includesupper and lower portions for receiving the U-shaped scraping element 39as shown in Figure 9. 'I'his element may be of felt or the like or ofany`other suitable material. 'I'he cartridge or container 38 ts betweenthe parts 31 as shown in Figure 7 so that it can be readily removed andanother one substituted for it. The plate 34 also carries a plurality ofspring lingers 40, as shown in Figure 8 for entering the grooves' 3I forremoving or partly removing coating material from said grooves. Theresiliency of the plate 34 tends to move the parts upwardly but thelimit of upward movement of the plate can be adjusted through means ofthe hollow screw 4I shown in Figure 4 passing through a threaded hole inthe section I1 of the arm and having a plunger 42 passing through itslower end engaging the plate 34. This plunger is preferably of brass orthe like and its enlarged upper end located within the bore of the screw4I is engaged by a spring 43 the tension of which is adjusted by a screwplug 44 threaded in the bore of the screw 4I.

An electromagnet 45 is located in av hole formed "of the article.

in the section I1 of the arm. and the screw 35 which connects the plate34 to the arm enters the core of the magnet and a bridge 46 connects theupper end of the core with the outer part of thescrew 4I as shown inFigure 4 so that when the magnet is energized the spring 34 will beattracted and moved upwardly, pushing the plunger 42 upwardly againstthe action of the spring 43 and then when the circuit to the magnet isbroken the spring 43 pushes the plunger 42 downwardly with considerableforce and also moves the plate 44 downwardly and this movement willdislodge any coating material from the scraper which has become hardenedand which would interfere with the scraping action upon the wheel. 'I'hecircuit 41 for the magnetic means is controlled by a switch 48 carriedby a part of the frame 49, as shown in Figure 10, the switch beingclosed by a cam 50 on the member 1 of the Geneva movement. switch is soarranged that it will be closed by the cam before the article A reachesthe application station so that the scraper will be clean when theapplication of the paint or coating material is being performed.

The invention also embodies vacuum means for holding the articles A inposition and as will be seen from Figure 13 the shaft 3 is of hollowconstruction and has its inner end with which the gear 4 is usedrotatably tting over the reduced part of a bored member 5I carried bythe table I and the bore of which is connected to a vacuum producingmeans by a tube 52. A bored shaft 53 has a frictional sliding t in theshaft 3 and projects therefrom and has a head 54 secured to its outerend. Said head is formed with a threaded nipple 55 to which ls threadeda bored mandrel 56, preferably of the shape shown in Figure 13 with itsinner end enlarged and of but slightly less diameter than the mouth ofthe article A asalso shown in Figure 13. A gasket 51 is held between thehead 54 and the mandrel and projects beyond the inner end of the mandrelto be engaged by the mouth 'Ihus a vacuum is created in the articlewhich holds the same in place against the gasket, the air from thearticle being drawn threaded to the outer end of the shaft 3 and i heldagainst movement by al lock nut 6I. An L spring member 62 is fastened tothe head 54 and engages the head 60 and limits outward movement of thehead 54 as shown in Figure 13. The frictional engagement of this member62 with the head 60 and the frictional engagement of the shaft 53 withthe interior of the shaft 3 prevents free outward movement of the head54 and the parts attached thereto but when the article A is pulleddirectly outwardly said head 54 and the parts attached thereto will moveoutwardly, thus opening the port 59 so as to break the vacuum within thearticle A and to permit it to be easily removed. Thus it is necessaryfor the article to be pulled directly outwardly before it can be removedfrom the mandrel.

It is thought from the foregoing description that the advantages andnovel features of the invention will be readily apparent.
